dano i teach faceting and start with the pavilion/bottom first then top/crown and start from tip to table, working my way up the stone and better control of centering. i have several pounds of Oregon sun stone i got in quartzite Arizona pow wow in 70’s and it all cuts beautiful. if you’d like to try something new and different in a cut i have my own design of my reverse brilliant that really awakes any stone. get in touch with me and i can send you a copy of it with cutting order(bottom first) and a piece of laser yag that will blow peoples minds when cut to it. firstname.lastname@example.org
p.s. i polish on tin with 50,000 diamond powder and water, both very slow speed.
